Agrilus zhongdian Jendek sp. n.

(Figs. 7, 16, 23, 31, 33, 34, 40)

Type specimens. Holotype 3, (EJCB): “ China, Yunnan 1994 Zhongdian 16–20.vi. leg. Šiška T. Spevár”. Paratypes (4 3, 4 Ƥ): 2 3, 4 Ƥ (EJCB), same data as holotype; 2 3 (EJCB): “ China –NW, Yunnan, cca 3600 m, road Deqen–Yanjing, 10 km W of Deqen, 1997, 28 °28'N 98°53'E, 21–22.vi. M. Trýzna et O. Šafránek lgt.”.

Type locality: China, Yunnan province, Zhongdian [25°48'N, 99°42'E].

Description of the holotype. Body medium-sized, golden-green, with silky lustrous, without distinct pubescence. Head large; eyes convex, not protruding beyond head outline. Frons and vertex moderately convex with feeble median impression, vertex distinctly spirally rugoso-punctate. Pronotum widest in middle, anterior lobe distinct but not projecting beyond anterior angles, sides evenly arcuate, posterior angles feebly obtuse. Disc flat, with two shallow median impressions, first one transverse at anterior margin, second one smaller and oval in basal half. Sides of disc obviously impressed; prehumerus absent. Marginal and submarginal carinae markedly convergent, joined at posterior angles, submarginal carina obsolete at both ends. Scutellum impressed on disc, with obliterated transverse carina. Elytral apices widely separately arcuate. Prosternal lobe (Fig. 31) robust, markedly protrusive outward, deeply, arcuately emarginate with sharply pointed sides; prosternal process (Fig. 31) narrow, with sharp angles, subparallel between coxae and clearly impressed on disc; metacoxae sharply protruding outward (antero-ventral view) (Fig. 40); basal ventrite distinctly, subtriangularly impressed between metacoxae. Aedeagus with median lobe distinctly pointed at apex and with smooth sides (Fig. 16). Legs long and relatively thin, metatarsi distinctly shorter than metatibiae; tarsomere 1 subequal in length to following two tarsomeres combined.

Sexual dimorphism. Females are generally larger and more robust with smaller, less convex eyes; prosternal lobe arcuately emarginate, without spines alongside emargination; metacoxae flat; basal ventrite without impression between metacoxae.

Variability. Maximum width of pronotum is around basal third in one paratype; prosternal process in one paratype has sides slightly expanding.

Measurements. Holotype: 7 mm, Paratypes 5.8 – 7.9 mm.

Differential diagnosis. This species is characterized by golden-green and robust body, flat pronotal disc; long legs; markedly protruding and spinate prosternal lobe (Fig. 31), form of prosternal process (Fig. 31) which is subparallel and narrow with, sharp angles, and most notably by the form of the median lobe of the aedeagus (Fig. 16).

Etymology. The specific epithet is a noun in apposition referring to the city of Zhongdian, the type locality of the new species.

Distribution. China (Yunnan).
